The aim of this study is to investigate practises and meanings regarding byhand and digital writing among digital natives under a micro-social approach that is related to New Literacy Studies. Taking the authors Chartier, Jenkins, Livingstone, Rivoltella and Caron & Caronia into account, this study, based on ethnographic research, focused on five carioca adolescents in their homes, during weekly meetings, keeping records of their interaction with computers connected to the Internet and by-hand writing. There has been an attempt to recognize not only production practises, but also representations and meanings that such adolescents construct from by-hand and digital writing and the comparisons teenagers make regarding such representations and meanings. Analysis of the empirical data has shown significant variation among writing to speak (related to the web, through the keyboard), writing for the self, writing for the other and writing to school. Such variations are associated to the support. It has been noticed a distinctive difference concerning gender when it comes to writing for the self: the adolescent girls see the paper as a locus for self- discovery and for the expression of inner feelings. To both genders online social networks are seen as privileged spaces to share experiences, based on synchronous and asynchronous messages exchange as resources of communication, but also on literary writing, from and to young people. Among such pieces of writing, fanfictions and webnovelas stand out.
